Title: Bone mill
Inventor: ISHIDA NORIYUKI
IPC: B02C18/22
Filed: 2000-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a bone mill of a novel mechanism capable of rapidly pulverizing bones to a sired sizing. SOLUTION: Respective cutter units 12 and 13 are provided with plural sheets of disks 15 arrayed at prescribed intervals in parallel. Knife blades 40 for pulverizing the bones are formed on the peripheral surfaces of the respective disks 15. The disks 15 of the first cutter unit 12 and the disks 15 of the second cutter unit 13 are so positioned as to be alternately fitted in spacings. The disks 15 of the respective cutter units 12 and 13 are rotated inwardly with each other. When, therefore, the bones to be pulverized are supplied to both cutter units 12 and 13, the bones are taken by the disks 15 rotated inwardly with each other into the spacings between the disks and the knife blades 40 of the disks 15 bite into the bones, thereby crushing the bones.  As the bones pass between the disks 15 of the first cutter unit 12 and the second cutter unit 13, the bones are pulverized by the disks 15 positioned to fit each other.

Title: Voice mail transmitted via packet network
Inventor: FOX JAMES H
IPC: H04M7/12
Filed: 2000-03-01
Abstract: PROBLEM TO BE SOLVED: To reduce electrical communication cost, that is related to leaving a voice message of a long distance call or a toll call on a different time base by providing a means which transmits a calling subscriber message to be reproduced later from a calling subscriber communication device to a called subscriber communication device via a 2nd network. SOLUTION: A communication network 100 includes a calling subscriber communication device 102 and a called subscriber communication device 104, and both the devices 102 and 104 perform mutual communication via a central station 106 of a public switching network or a communication link 108 of a packet switching network. When a calling subscriber leaves a message for a called subscriber who cannot answer the call, the communication is automatically switched to a network of higher cost and then the calling subscriber transmits a message, that is to be reproduced later by the called subscriber via a packet network of lower cost. As a result, the duration is reduced for a tall call on a time base, that is transmitted via a public switching network of higher cost, and accordingly the total cost of communication is reduced.
